MECHANISM FOR MIXING AND MEASURING MATERIALS.

SPECIFICATION formingpart of Letters Patent No. 666,841, dated January 29, 1901. Application filed May '7, 1900- Serial No. 15,734. (No model.)

To a, whont it may concern.-

Be it known that I, HORACE L. ARNOLD, a citizen of the United States, residing in New York, (Brooklyn,) in the county of Kings and State of New York, have invented certain new and useful Improvements in Mechanism for Mixing and Measuring Materials, of which the following is a specification.

My invention relates to measuring, mixing, or stirring mechanism; and, primarily, the object thereof is to provide means for delivering a measured quantity, which may be Varied as desired, of either liquid or pulverulent inaterial at the desired intervals of time.

A further object of the invention is the provision of mixing and measuring mechanism and air-supply means cooperating therewith, the air being, while the mechanism is in use, under constant pressure from any desired source sufficient to expel a predetermined charge of material and to force it to the point where it is to be utilized A further object of the invention is the pro= vision of a receptacle or casing in which the measuring and mixing or stirring devices are mounted, said casing, when the mechanism is in use, being kept constantly filled with the material to be delivered and also having supply and discharge openings and an opening through which suitable pressure means may be introduced. I

A further object of the invention is the provision, within a casing or chamber containing the material to be delivered in measured charges, of a movable device having a series of pockets for receiving such material, from which pockets the measured charge is forced.

A further object of the invention is the provision, within a casing or chamber containing the material to be delivered in measured charges, of gearing for rotating a wheel or carrier having a series of pockets for receiving the material contained in said casing and the teeth of which act as heaters or stirrers to mix and churn the material, and 'thereby,in case of a liquid, keeping its constituents thoroughly intermingled, and in case of a powder thoroughly stirring the same through the path through which the wheel travels to prevent packing within the casing or chamber at points adjacent to the carrier.

A further object of the invention is the provision, in connection with a geared pocket wheel or carrier within the casing, of means for either partially or wholly obstructing the delivery of the contents of the pockets of said wheel.

A further object of the invention is the provision, in connect-ion with a casing containing material to be delivered, of a shaft for supporting gearing adapted to be driven at any desired speed, one of the members of said gearing being in engagement with the teeth of a pocket wheel or carrier for receiving fixed charges of material and in connection with this pocket-wheel to provide a movable valveplate or valve-plates covering a portion of the pocket wheel and adapted to be adjusted either to open, partially close, or completely close a pocket in said wheel or carrier when it comes into line with a pressure-receiving opening and a material delivery opening formed in the casing.

Referring to the accompanying drawings, Figure l is an end elevation of my invention, showing by dotted lines a material-supply tank and an air storage or pressure tank connected therewith. Fig. 2 is a side elevation of the invention. Fig. 3 is an end elevation of my improved mechanism with the front plate of the casing or chamber removed. Fig. 4 is a section on line a a, Fig. 3, looking in the direction of the arrow. Fig. 5 is a vertical section on line b b, Fig. 3, certain parts being shown in elevation. Fig. 6 is a horizontal section on line d d, Fig. 3. Fig. '7 is a detail view, partially in section, showing the pocket wheel or carrier and the means for varying the area of or closing the passage by which material is delivered from thepockets of said wheel or carrier. Fig. 8 is a similar view showing the valve-plates adjusted partially to cover the pockets in the wheel or carrier as they pass between said plates. Fig. 9 is a sectional view on line e 6, Fig. 7, looking in the direction of the arrow. Fig. 10 is a de tail view in perspective of a sleeve for-partially inclosing one of the gear-wheels within the casing. Fig. 11 is a side elevation of the air-supply pipe detached, showing the flange and collar thereon. Fig. 12 is a section on line ff of Fig. 9; and Fig. 13 is a view, partially in section and partially in elevation, of a device for feeding pulverulent material to the casing of the machine.

Like numerals designate similar parts throughout the several views.

Referring to the drawings, the numeral 5 designates a casing or chamber (the main body of which may be in the form of a single casting) having a detachable end plate or cover 5, a base 5 a sleeve orcoupling 6 for receiving a pipe 7, through which the material to be mixed, stirred, and measured is delivered to the casing, a tubular boss 8 for receiving the air-supply or other pressure connections, and tubular projections 9 and 10, through which shaftshereinafter described are passed.

Journaled in the tubular boss 9 of the casing is a shaft 11, the outer end of which is splined to a gear-wheel 12, and to the inner end of said shaft a long pinion 13 is secured. \Vithin this tubular boss 9 and surrounding the shaft 11 suitable packing 14 is placed, which will prevent the leakage of material from the chamber within the casing along the shaft, a further packing (designated, respectively, by 15 and 16) being mounted within a compartment of the casing adjacent to the inner end of the shaft 11 for a similar purpose, and this last-named packing may consist of perforated disks of vulcanized fiber and felt, or any other suitable material may be employed as a substitute therefor.

Passing through an opening in the rear wall 5 of the casing is a tube 17, having an axial bore of suitable size, and at its inner end, within the casing, said tube is provided with lateral projections 18 and 18, for a purpose hereinafter set forth.

Bolted to the projections 18 and 18' of tube 17is a plate 19, having a tubular extension 20, the bore of which is of different diameters. Plate 19 is perforated to receive bolts 21 21 and is separated from the projections 18 and 18 by sleeves 22 and 22, through which the bolts pass as they enter threaded openings in said projections 18 and 18, as seen in Fig. 6.

Journaled on the sleeve 22 is a wheel or car rier 23, having a series of pockets 24, which may be of any desired configuration, the hub 23 of said wheel being of less length than the sleeve. As illustrated, these pockets are shown of circular form; butit is distinctly to be understood that the invention is not limited to the specific form represented, for the shape of the pockets may be widely varied without departure therefrom. The teeth of this wheel or carrier 23 are in mesh with the pinion 13 of shaft 11, the gear-wheel 12 of which may be driven at any desired speed; but any other desired means may be employed for actuating said wheel or carrier either in a rotary or partially rotary direction.

Sleeve 20 is chambered at 20 to receive a helical or other form of spring 25, which bears against a shoulder 26, carried by an air-supply pipe 27, and this pipe is provided with a flange 26, which bears on one side against the plate 19 and at its opposite side against a valve or material-delivery-regulating plate hereinafter described.

It will be noticed that the tendency of spring 25,which bears at its outer end against a shoulder of the sleeve 20, is to force the flange 26' closely against the valve-plate 34 to provide a tight fit and prevent leakage of material between the wheel or carrier and plate, and as an incident of this action the gear-wheel 23 and valve-plate 34 are also caused tightly to engage the adjacent devices for the same purpose. The valve-plate and the pocket wheel or carrier are supported for free lateral movement to permit play of said parts in either direction, whereby close contact is made of the valve-plates 34: and 34, the pocket wheel or carrier 23, the charge-delivery tube 17, and the air-pressu re tube 27 through the action of the single spring 25, contained in the chamber 20', and no material other than that contained in the pockets of the wheel can enter said charge-delivery tube 17. By this constructionthe mechanism is made both automatically to adjust itself when first assembled and constantly to adjust itself to take up wear while in operation, and to enable this action to take place the hub of the pocket wheel or carrier 23 is made of less length than the sleeve 22' and has a limited lateral play in either direction between the projection 18 and plate 19, as illustrated in Fig. 6.

Sleeve 20 is reduced at 20 and surrounding this reduced portion is packing 27, compressed by a follower 27, which is actuated by a nut 28, threaded into the boss 8 of the casing, as shown in Fig. 6, thereby to prevent leakage of material through the front of the casing. Whatever pressure is placed upon the packing is transferred through all the assembled parts specified, and the result is a tight fit, preventing leakage or seepage of the material, which, if permitted, would preclude a charge fixed in quantity from being delivered. Connected with the air-supply pipe 27 is a coupling 29, in which a pipe 30, leading to any suitable source of air-pressure-as, for instance, the compressed-air tank 31, (see (lotted lines, Fig. 1)is mounted, the supply of air being regulated by a valve or other suitable device 32, (also shown by dotted lines in Fig. 1,) carried by said air-pipe. My inven-- tion, however, is not limited to any specific means for supplying air constantly under pressure, for ordinarily an air-pump will be utilized for this purpose.

Journaled in the tubular projection 10 is a shaft 32', packed at 32", to which shaft a handle 33|isapplied,and this shaftis equipped at its inner end with a disk 32, carrying a wrist-pin 32 which works between the walls of slots in the valve-plates 3t 34:, mounted for swinging movement about thepinion 13, each of these valve-plates being provided at its end remote from the wrist-pin with an Opening 34 and 34 respectively, which openings are adapt ed to register with the pockets 24 in the wheel or carrier 23 as it rotates between said valve-plates or entirely to close or partially close said pockets 24 as they pass between said plates and carry the material to be delivered by the air-jet device shown or otherwise to the tube 17, leading to the place where the respective charges of material are to be utilized. These valve-plates by occluding more or less of each pocket of the carrier as it, filled with material, approaches the passage between the air-supply tube 27 and the material delivery-tube 17 permit the charges to be regulated with nicety, and anydesired part-of the material contained within one of the pockets of the pocketwheel may be delivered'as a fixed charge to the place where said charge is to be utilized.

A sleeve 35, having a flange 35, is loosely mounted on the driving-pinion 13 and is free to slide endwise thereupon, and to the flange 35 the valve-plate 34 is secured by rivets or otherwise, as shown in Fig. 12, while the other valve-plate 34 is loosely mounted upon the sleeve 35, so that both valve-plates are free, so far as their support is concerned, to move in either direction fora limited distance. The sleeve is cut out enough on one side to permit the pinion to mesh with the teeth of the pocket-wheel and drive the same. valve-plates might, however, be mounted on a fulcrum otherwise placed and constructed,-

the pinion being used as a valve-plate fulcrum because of convenience and simplicity of construction,or other valve mechanism may be employed without departing from the invention, which is not limited in this respect.

It will be noticed that spring 25, hearing against the shoulder 26 of air-tube 27, tends to force with considerable pressure the plate 34 against the side of the pocket-wheel and to force the plate 34 tightly against the end of the delivery-tube 17, thereby causing a close fit between the parts and preventing leakage of material from the contents within the casing from adding an increment to the measured charge to be delivered, and thus causing inexactness of quantity in the measu red charges. v

When the device is to be employed for feeding pulverulent material, the tube 7, connecting the interior of the casing with the liquid-supply tank-40, (shown by dotted lines in Fig. 1,) is removed and a tube 41, connected with a tank 42 for containing said pulverulent material, is fitted Within the socket of.

the tubular boss orprojection 6, and mounted within this tube 41 is a shaft 43, carrying a worm or other suitable device 44,- driven by a pulley 45, said worm serving to feed the pulverulent material to and causing it to fill the casing.

In the operation of my improved mechanism when fluid is to be forcibly delivered in measured charges from the'casing the valve The 32 (see Fig. 1,) carried by the pipe 7, is opened and a fluidfor instance, kerosene or other hydrocarbon-is fed by gravity to fill the interior of the casing 5 completely, and when it fills said casing the shaft 11 issct in motion at the desired speed by gear-Wheel 12,

intermeshed with any suitable driving mechanism, and the pinion l3 ofsaid shaft engages withthe pocket wheel or carrier 23 and rotates the same. As this wheel or carrier is rotated the teeth thereof continually stir or churn the material contained within the casing and in case of a hydrocarbon keep the constituents thereof thoroughly intermingled. Furthermore, the valve-plates 34 and 34are so positioned that a tight fit is had on each side of the wheel or carrier, and the lighter layers of the hydrocarbon, which naturally are at the top thereof, are prevented, from en-. tering the pockets in the wheel or carrier, and the supply to said pockets is always from the bottom layers, which are of the greatest specific gravity. In this way when a hydrocarbon is employed charges containing heavier-constituents of material are first supplied, and as the wheel or carrier rotates and brings one of the pockets into a line to register with the openings in the air-supply pipe 27 (when such a pressure device is employed) and the charge-delivery pipe 17 said charge is atomized by the air and forced from the pocket to the point where it is to be utilized.

Wheel or carrier 23 may of course be driven at any desired rate of speed, and if the valveplates 34 and 34 are set to more or less cover the openings in the pockets as they pass by the registration-points between said tubes 17 and 27 it will be readily seen that a charge of less than the full cubic contents of one pocket of the pocket-wheel may be supplied to the point where it is to be utilized.

If pulverulent material is employed, the tube 7 and liquid-supply tank 40 are removed from the casing and the tube 41 and supply tank 42 applied thereto, the pulverulent material being, as above stated, positively fed to fill the casing by the worm or screw 44 or by any other suitable device which may be substituted therefor. When this class of material is employed, the teeth of the wheel or carrier 23 act in some degree as stirring devices to prevent the packing of such material Within the casing adjacent to the wheel or carrier, and when the filled pockets of said Wheel or carrier come consecutively into line with the openings in the air-pipe 27 and charge-delivery pipe 17 the air being under constant pressure immediately forces the Whole or part of the charge contained in any pocket to the delivery-point.

While my invention is not limited in use, yet I have found in practice that it is well adapted for supplying charges of material to what areknown as internal-combustion engines, and it is well-adapted tofeed either liquid fuelas kerosene or gasolene-or powdered fuel-as wheat-flour, cornmeal, or wooddustto said engines.

While the measuring wheel orcarrier 23 is shown pierced with a circle of holes or pockets equally spaced and concentric with the axis of said wheel and said pockets will be filled with the material contained in the casing as said wheel revolves, yet it is distinctly to be understood that the form, character, or size of said pockets is immaterial and that they may be of different shapes from those illustrated by the drawings and also differently arranged with respect to the wheel.

The thickness of the measuring wheel or carrier and the diameter of the measuring holes or pockets may be such that the cubic contents of each hole or pocket will equal the maximum bulk of each single charge to be delivered, and while means are shown for isolating the contents of each measuring-wheel hole or pocket from the surrounding and adjacent bulk of material contained in the closed casing 5, yet the exact number of measuring holes or pockets covered by the isolating-plates is not of particular importance; but at least one hole or pocket must, however, be completely covered by said isolating plates or valves 3 and 34, and more than one of said measuring holes or pockets may be so covered. Generally speaking, the greater the number of measuring holes or pockets exposed to the bulk of the material in the easing the greater the probability that each of said holes or pockets will be fully filled by the surrounding material in the casing as the measuring wheel or carrier revolves. \Vhile I have shown as a means for effecting the translation of the contents of the isolated measuring hole or pocket inclosedbetween the valve-plates 3a and 34 an air-pressure tube 27 and a charge-delivery tube 17, yet it is distinctly to be understood that these means may be variously modified and other means than air-pressure may be employed, if desired, for forcing the charge of material from a pocket in the wheel or carrier 23 to said charge-delivery tube 17.

In case the measuring and mixing mechanism is employed for feeding charges of fuel to a combustion-motor the tube 27 is in the construction illustrated supplied with constant air-pressure from the storage-tank 31 or otherwise, and the pockets of the measuring wheel or carrier being filled with material a certain part, variable at the will of the operator, of the contents of one measuring-wheel hole or pocket will at the required time be atomized by the air-pressu re and driven to the extremity of the delivery-tube 17, which in the instance noted would be made to connect with the charge or intake passage leading to the motor-cylinder.

WVith the present forms of combustion-motors in which gasolene or other hydrocarbon is employed as fuel it is well known that the forms of carbureter now used draw off first the more volatile elements of the hydrocarbon, leaving the heavier parts, which less readily combine with air, until the last, and thus produce undesirable changes in the constitution of the charge to be delivered to the motorcylinder. By placing the material supply tank, as shown in the drawings, above the casing 5 the operation is always to fill said casing from the heaviest part of the fluid contained in the tank, and the measuring wheel holes or pockets are filled from the bottom of the hydrocarbon contained in the casing, and in consequence of this gravity arrangement it is impossible to supply the motor with the lighter parts of the contents of the supply tank or casing first, and hence by the means described I am enabled to insure a fairly-constant charge constitution, which is the first essential in uniform internal-combustion-motor performance.

Many of the details of the mechanism shown and described may be variously modified without departure from my invention, and it is not limited to the precise construction shown. The measuring wheel or carrier may be variously mounted for movement and may be driven at one speed or another speed, as desired, and so, too, the valve-plates shown and described may be variously modified without departure from my invention, which is not, as above stated, limited in this respect to the details shown and described either as regards said plates or the means for operating the same.
